【Abstract】 HEHEHP and Cyanex 272 were selected to form a mixed extraction system. The extraction capacity,the stripping acidity and the separation factors between each two neighboring Rare Earth elements were determined. The optimum component of the system was determined. The major elements,which affect the performance of the extraction system,were investigated.更多还原
